The right turn signal stopped rapid flasing, but now the horn will not work? What is the problem? How do I fix this?
Horn relay under the hood or blown fuse
Cruise an horn an alarm not working
check the fuses, then the relay,but before buy a new horn, disconnect the horn, it's behind the bumper on drivers side. It has one bolt holding two horns. take the connecting wires off and clean. I used a small file and cleaned the contacts. it worked for me
